Abstract

To improve properties of epoxy composites, surfaces of the illite and carbon nanotube (CNT) were treated by fluorine gas. The fluorinated illite and CNT were then characterized by X-ray photoelectron microscopy (XPS) and the mechanical and thermal properties of their composites were evaluated. The tensile and impact strengths and thermal stability of the composites increased upto about 59%, 18% and 124%, respectively compared to those of the neat epoxy. Improvements of mechanical and thermal properties in the composites were attributed that the fluorination of illite and carbon nanotube helps to enhance the dispersion in epoxy resin and interfacial interaction between them.

에폭시 복합재의 물성을 향상시키기 위하여, 일라이트 및 탄소나노튜브가 불소 가스로 표면처리 되었다. 불소화 처리된 일라이트 및 탄소나노튜브는 엑스선 광전자 분광기를 이용하여 분석하였고, 그 복합재의 기계적 및 열적 특성을 평가하였다. 이 에폭시 복합재는 미첨가 에폭시 복합재와 비교하여 인장강도는 약 59%, 충격강도는 18%, 열안정성은 124%로 크게 향상됨을 확인하였다. 에폭시 복합재의 기계적 및 열적 특성의 향상은 일라이트 및 탄소나노튜브의 불소화가 에폭시 내에서 분산성을 향상시키고 에폭시 수지와의 계면 결합력을 증가시켰기 때문이다.
